the precision of the value associated with objects such as line or polygons (by default: double)

The elements in the VectorData have their coordinates in the projection specified by the WKT string. This class also offer the possibility to store the coordinates directly into an image coordinate system, using the origin and spacing in a similar way as the corresponding image.

Graft the data and information from one VectorData to another. This is a convenience method to setup a second VectorData with all the meta information of another VectorData and use the same DataTree Note that this method is different than just using two SmartPointers to the same VectorData since separate DataObjects are still maintained. This method is similar to VectorDataSource::GraftOutput().
